Infra-Red and Raman Spectra of Fluorinated Ethylenes. I. 1,1-Difluoroethylene

Abstract

The infra-red absorption of CF2:CH2 gas has been investigated between 2 and 22.7μ with a prism spectrometer of high resolution. The Raman spectrum of the compound in the gaseous state has been photographed with a three-prism glass spectrograph of linear dispersion 15A/mm at 4358A. The 12 fundamental vibration frequencies have been assigned and the observed spectra have been interpreted in detail.
